Horse collapses at Knott's Berry Farm stagecoach ride

Officials at Knott's Berry Farm were trying to determine why a horse collapsed during the stagecoach ride, according to a KTLA report.

A woman told the station that the animal appeared exhausted before it began to tremble and collapse Sunday.

"It was kind of like getting dragged this way," Lindsey Herrod said of the animal, which was harnessed to other horses for the ride.

"In the meantime, [another] horse is trampling on it, and I think he was trampling on his face," Herrod said.

KTLA reported that it received an emailed statement from Knott's Berry Farm that said: "The horse received medical attention that night, but the veterinarian in attendance was not clear as to what caused the fall. The horse is still under doctor's care until we can determine the root cause of the animal's behavior."
